There is this thing that people do on Twitter. Write stories, or snippets, in 140 characters. Here is a guy that is really popular for his stories. If you read through them you get a sense of his most recent fixations - sex, tension, bodily functions. More interesting then the usual twittery twit, and a peephole into the unedited/edited mind.
I wonder if there is a PHD candidate out there writing a paper on this type of reveal?
Hemingway's shortest piece ("For sale: baby shoes, never worn.") is 29 characters. Less really can be more.
